Atrial appendage occlusion devices and cardiac monitoring positioned within the left atrial appendage and/or left atrium. In some embodiments the devices include an anchoring portion adapted to anchor the device in place adjacent the left atrial appendage, the anchoring portion comprising distal deformable anchoring portion adapted to be deployed in the left atrial appendage and a proximal deformable anchoring portion being adapted to be deployed in the left atrium, a barrier element secured to the anchoring portion and adapted to cover the left atrial appendage when implanted, and adapted to prevent blood clots from passing through the barrier element, and a cardiac monitoring element secured to at least one of the anchoring portions, the monitoring element including one or more sensors within in the left atrial appendage and/or left atrium and adapted to monitor left atrial cardiac data.

An occlusive device includes a covering component configured to modulate passage of blood or thrombus therethrough, and an occlusion frame that includes a plurality of elongate occlusion frame members. The elongate occlusion frame members are arranged to form a generally disc-shaped member. The occlusion frame is at least partially covered by the covering component. The device further includes an anchor frame that includes a plurality of elongate anchor frame members. The device further includes a first hub component from which the elongate frame members extend, and a second hub component from which the elongate frame members extend.

Apparatuses and methods for use in surgical vascular anastomotic procedures. Apparatus includes a blood vessel inner wall (BVIW) sealing and hole forming device, and a hole forming actuator. BVIW sealing and hole forming device includes a hole sealing device, and an anastomotic hole generating device. Hole sealing device includes a sheath that fully encloses and holds a self-expanding hole sealing assembly, a manual hole sealing controller assembly, and a flexible control wire enclosed within a flexible tube. Anastomotic hole generating device includes outer and inner assemblies, with a conically shaped anastomotic hole generating member. Hole forming actuator includes outer and inner assemblies. Also disclosed are procedures for performing surgical vascular anastomosis using the disclosed apparatuses and methods. Particularly applicable for use in clampless types of (end-to-side) surgical vascular anastomotic procedures, for performing coronary artery bypass grafting (CABG).

Closure devices that selectively control blood flow between the right atrium and the left atrium of a heart of a patient. The control of blood flow can be based on detected values from a pressure sensor. The closure devices can include a body configured to engage native tissue when the device is deployed across the septal wall. In a first state at least a portion of (an inner surface of) a lumen is closed, preventing blood flow through the closure device. Ina second state, the lumen is open to enable blood flow from the left atrium to the right atrium. A closure element can be selectively adjusted to control the flow of blood through the lumen. A volume of an expandable chamber can be increased or decreased to place the closure device into the first state or the second state.

An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame and a covering material. In some embodiments, the frame includes a single continuously wound wire that defines an apposition portion, a defect-occupying portion, and a sealing portion. In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the GI tract including the small bowel and colon. In some embodiments, a two-part frame construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame.

A method and devices for relieving pressure in the left atrium of a patient's heart is disclosed. The method includes using an ablative catheter in a minimally invasive procedure to prepare an opening from the coronary sinus into a left atrium of the patient's heart. Once the opening is prepared, the opening may be enlarged by a technique such as expanding a balloon within the opening. A stent is then placed within the coronary sinus of the patient, with a transverse portion expanding within the opening, allowing blood to flow from the left atrium to the coronary sinus and then to the right atrium. Pressure within the left atrium is thus relieved.

An occluder includes a proximal occlusion portion. The proximal occlusion portion has a proximal end provided with a first converged member, and is provided with a conical guide structure on an outer periphery of the first converged member. The guide structure has an inner diameter gradually decreasing from a distal end to a proximal end. The guide structure provides a guiding performance to facilitate the occluder to be withdrawn into the sheath easily. An occluder fastening system is used in cooperation with the occluder.

A septal closure device includes a frame comprising one or more tissue anchor features, an occluding membrane, and a pressure sensor device attached to the occluding membrane.

A medical device including a removable frame and biomaterial cover, methods of assembling and using the same, and a delivery system including the same are described herein. The medical device includes a frame having proximal and distal ends, the frame including a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment having a proximal end and a distal end connecting the proximal and distal discs. Each of the proximal and distal discs includes a respective plurality of prongs and has a maximum cross-sectional dimension larger than the connecting segment. The medical device further includes at least one biomaterial cover including an outer section and an inner section defining a cavity therebetween, wherein at least one of the proximal and distal discs of the frame is positioned in the cavity.

The present invention is related to an occlusion device for occluding an opening in a body tissue and a method of deploying said occlusion device to the site of defect. The occlusion device comprises a flexible proximal high-pressure disc and a flexible distal low-pressure disc, that are centrally connected by a central connector section of varying diameter and length which further comprises a stretchable narrow connector at the tapered end, and retention screws. The design of the occlusion device of the present invention is such that it enables haemodynamic adjustment providing a better-fit to the size of the defect, and reduction of clamping force and stress on the conduction system.
